Application filed May 12, 1909. Seria1.No. 495,48'

To all whom it may concern: Be it known that L FRED A. NEIDER, a citizenof the United States of America, and

resident of Augusta, county of Bracken,

In the accompanying drawings I have illustrated a nail. embodying myinvention, and have given views of it in the course of Referring to thedrawings: Figure 1 is a side elevation of an ordmary wire nail. Fig. 2is a similar view of the same with the shoulder upset thereon, adjacentto the head. Fig. 3 is. a perspective view showing the washer in theprocess of being driven to place adjacent to the shoulder. Fig. 4 is aperspective view of the complete na1l of my invention.

Startinggwith the ordinary wire nail, A, a shoulder, is formed thereonby upsetting the nail. This shoulder, B,.is formed with an abrupt ridge,b, between it and the shank,

a, of the. nail. vWasher, D, is lar er in diameter than the head, a, ofthe nai is made of hard metal, such as tempered steel, and has, acentral erforation, d, which is of a diameter sligh y less than thediameter of-the shank, a, so that the washer, D, has a dl'iV,

ing 'fit upon the shank, a. Washer, D, is

driven onto the shank, a, so'as to contact the shoulder, B. When thenail embodying my invention is fully driven into a timber, washer, D,seats against the outer face of the timber. Heavy blows may be rainedupon the head of the nail, without sinking the washer into the timber,and without causin 'the Washer to be spread by the shoulder. ere thewasher of the size of the head of the nail, it would be driven into thetimber by blows such as are required to draw the timbers being joinedsecurely together, for the reason that the head, a,;is more exposed tothe full blow of the hammer than in an ordinary nail when it is drivento place, because in the latter case, the head becomes flush with thetimber, which then contacts part of the head of the hammer.

of hard metal, has a driving fit upon the shank, a, and the meeting edgeof the shoulder, B, is abrupt, thereby making a firm seat against whichthe washer abuts. What I claim is: y I The combination of a nail havingnear one end an enlargement capable of being formed by upsetting themetal, and a hard metal washer fitting the shank of the nail snuglyandabutting against the shoulder, whereby the washer is adapted towithstand the force of blows necessary to draw timbers together byblows-upon the nail. v I
